S550 Mustang Update: Brake Tech, Autox, Time Trials, and Champagne!

In this mega-sized Forum Thread Update covering our S550 Mustang development (lately using our shop 2018 Mustang GT) we cover 5 more track days, Terry’s first autocross in the ’18, some brake system changes/tech/testing, and more.

We ran the car with NASA at COTA (above), with Optima at NOLA (below), with SCCA (Club Trials and Track Night in America), and even did some private testing on a road course (our 4th test at MSR-C). The good, the bad, and the ugly from each of these events is covered in this round – with some nice wins and a few “non-wins”.

Some valuable lessons were learned about brake hydraulics after track testing the factory PP1 15″ brake upgrade with the base GT brake master cylinder and booster on our ’18. A bit frustrating where we learned that (at a televised Optima event!) but it was soon fixed and track tested 3 more times after upgrading to the PP1 hydraulics and booster.

This update is chock full of dozens of pictures, many videos, and lots of other late model Mustang tech. Enjoy!
